摘　　要：传统的脱氮除磷联合工艺,往往因为除磷、脱氮两方面固有的矛盾性使处理出水的氮、磷含量不能同时达标.反硝化除磷新理论的提出,及以此为理论指导的连续流H ITNP双污泥工艺的设计开发为有效解决这一矛盾问题提供了新对策.利用人工合成污水,对新开发的H ITNP反硝化脱氮除磷工艺进行了研究.发现C/TN、C/TP、MLSS、SRT、DO和pH值等运行参数对工艺处理效果有较大的影响.试验结果表明,选择合理的运行参数,该工艺对NH3—N、TN、TP和COD的平均去除率分别达到96%,84%,90%和93%.In the traditional combined nitrogen and phosphorous removal process, the nitrogen and phosphorous can not be up to scratch because of contradiction of nitrogen and phosphorous removal. This problem can be solved by the denitrifying phosphorus removal and the HITNP process which is based on the theory. This paper studies on HITNP process for denitrifying phosphorus and nitrogen removal by using artificial waste water. It is found that operation parameters such as C/TN, C/TP, MLSS, SRT, DO and pH value have more important effects on treatment of process. The results showed that the average removal rate for NH3-N, TN, TP and COD has reached 96%, 84%, 90% and 93% respectively by selecting right operation parameters.
